SANTA ROSA, COAHUILA, MEXICO. No. 29. 



Iron, H. Fragment, weighing 19.3 grams, from a mass brought 

 by N. T. Lupton from near Santa Eosa, State of Coahuila, Mexico. 

 It was stated to have been found in 1837, in the desert between Santa 

 Rosa and the city of Chihuahua, and to have been brought into Santa 

 Rosa by a Mexican named Juan Garca. The original mass was ir- 

 regular in outline, the dimensions being about 33 by 28 by 21 cm., 

 and the estimated weight 8.73 kilograms. An analysis by Lupton 

 yielded :
